“…CNG has been considered as one the best solutions for fossil fuel substitution because of its inherent clean nature of combustion [13][14][15]. It has now been recognized worldwide as environment-friendly fuel [16,17]. Following are the main features which conduced to an increased interest to use natural gas as a transportation fuel:…”

“…Transit bus fuel economy is more readily available. According to Watt (2000), Chandler et al (2000), Chandler et al (2006), and Barnitt et al (2006), current dieselfueled transit buses are 20% more fuel efficient than CNG/LNG-fueled buses. However, this advantage is likely to drop as manufacturers equip new diesel buses with particulate traps and other controls in order to meet stiff 2010 emissions standards.…”

online ordering: http://www.ntis.gov/ordering.htm Printed on paper containing at least 50% wastepaper, including 20% postconsumer waste iii Acknowledgements Funding for this report came from the Clean Cities activity within the U.S. Department of Energy Vehicle Technologies Program.This report has greatly benefitted from the time and insight shared through personal communications with various fleet operators and industry specialists as indicated in the bibliography.The author owes a particular gratitude to Rob Adams with Marathon Technical Services. Rob shared his extensive knowledge of building and operating compressed natural gas refueling stations by patiently answering numerous questions, sharing his station cost calculator, and reviewing multiple drafts.All assumptions and any inaccuracies are the responsibility of the author and not the experts acknowledged above.iv IntroductionCompressed natural gas (CNG) vehicle projects can be highly profitable, or they can lose money, depending on numerous aspects of the fleet and station. To assist fleets and businesses in evaluating the profitability of potential CNG projects, the National Renewable Energy Laboratory (NREL) built the CNG Vehicle and Infrastructure Cash-Flow Evaluation (VICE) model. The VICE model demonstrates the relationship between project profitability and fleet operating parameters. This report describes how NREL used the VICE model to establish guidance for fleets making decisions about using CNG.The first section establishes a base-case scenario for three fleets that commonly use CNGtransit buses, school buses, and refuse trucks. This base-case tries to represent the average or most-common parameters affecting the CNG project's profitability for average fleets of each type.The second section uses the model to show how specific project parameters (such as station cost or price of fuel) change profitability from the base-case. The section then prioritizes these parameters to help fleet operators understand the most important factors affecting the business case of the project. Through a question-and-answer format, this section presents common CNGrelated questions answered by NREL using the VICE model.The business case targets municipal governments, which operate fleets suited well for CNG vehicles because they drive circular routes that enable refueling at the same station. These fleets are transit buses, school buses, and refuse trucks. Municipal governments are also targeted because their primary goal is to improve their residents' quality of life. This goal allows the government to utilize all the advantages of CNG, including long-term cost-effectiveness, moreconsistent operational costs, increased energy security, reduced greenhouse gas emissions, reduced local air pollution, and reduced noise pollution. A forthcoming report will focus on private fleets that are suited well for CNG, such as taxi cabs and delivery trucks.
